China, Mcdowell, NPR discussed on All Things Considered


50 from NPR news. This is all things considered. I'm Elsa Chang and I'm Sasha Pfeifer. Let's say it's 2021. Scientists have already developed and marketed a vaccine for Coben 19. Now they face a new problem convincing people to actually get vaccinated with it. A Gallup poll last month found that more than one in three Americans would not get an FDA approved Corona virus vaccine even for free. Psychology professor Delores Albarracin studies behavior and medicine at the University of Illinois at Urbana Champagne. She spoke with our co host, Audie Cornish earlier today about why some people are skeptical of vaccines. We know that it can take years to develop and distribute a safe vaccine to everyone. And then, of course, just this week, the pharmaceutical company AstraZeneca announced that it was hitting pause on its trial to investigate and unexplained illness in one of its participants. So there are people who are concerned about potential long term side effects that who are worried about this process being rushed. Does that boost people's doubts? And is that wrong? Well, I think it's completely normal, and we should all be looking at side effects for any pharmaceutical product that we consume right. Among those who hesitate 60% fierce side effects 37%. I'm not afraid, but to some think it will work. And then you have trained per cent who are pissed on two posers. So the anti Vax group and that's a small group. So for their folks who are fearing side of facts. I think news like the one you're referring to are going to be extremely influential, and they connect with Some pre strong and persuasive in narratives about Big pharma. And we have data even want my own day that with colleagues at the University of Pennsylvania showing that exposure to social media earlier on actually predict vaccination intentions in the domain, a fool later on, so there's pretty good data that those groups are not trivial. Wait, So help me understand this Essentially if someone sees anti vaccination social media posts that can actually influence their own decision about whether or not to accept a vaccine. Yes, it's similar to that. So he surveyed 3000 participants over one year following the flu season till months. So when we observe is what is going on Twitter. What misinformation amount vaccines is being distributed and where So when you look in that, and then you look at whoever lives in the county that has that kind of big pharma conspiracy in this information circulating on Twitter. Are less likely to get the flu shot a few months later. Except Dad. They're not affected if they have discussions in really life, so if they can discuss this information with friends, family their physicians, then they're less persuaded by the misinformation, but otherwise the misinformation they encounter regionally affect them. What does all this mean for the public information campaign? How should authorities. Public health officials go about trying to convince people to embrace the vaccines should one come along? So this travesty In my view should be to communicate a norm clearly. So you need to tell people that everybody wants it. We all like it. We must have it. So something quite different from what we saw with wearing masks were there was a lot more hesitation in the messaging, right and contradictions, Silver months. So clear norm. You also need to be, of course, correcting for misinformation systematically every day through health education in schools and work. Everywhere. I'm seeing an explosion of misinformation and what the whole has referred to as an infant Emmick, and if we don't eradicate it won't make invade difficult to end a coffin 19 pandemic. That was the Laura's other scene. She's a professor at the University of Illinois at Urbana Champagne. Thank you for speaking with us. Thank you. China's military appears to have successfully tested a new spacecraft. Last week's mission was shrouded in secrecy. But as NPR's Jeff from field reports, there are some clues about what China sent into space and why. Last Friday, a Chinese rocket took off carrying a mysterious payload. A terse statement on state media said it was quote A reusable experimental spacecraft, but they didn't give a launch time. They don't have any more details. No riel official footage of the Lord's Jonathan Mcd, Alison astronomer, Earthy Center for Astrophysics, Harvard and Smithsonian who specializes in tracking satellites and spacecraft orbiting the Earth. When he plotted the course of China's new craft, he found that it passed over a secretive military facility. An area called Loop Nure, where China once tested its nuclear weapons. There's an air base there, which has AH big runway that's aligned exactly in the direction ofthe the orbit of the space craft. On Sunday, China announced its new spacecraft head landed sure enough fuzzy satellite images snapped by a commercial company called Planet. Seemed to show activity on the giant runway right at the moment, the landing would have occurred. McDowell says that the evidence is circumstantial, but he believes China has just tested a space plane. Think of it. It's a little space shuttle a craft with wings probably too small to carry people that took off on a rocket and coasted back to Earth. The information of all hands together now that this wass A test of something probably a space plane that made a winged reentry on landed on the runway at Lop nor the US Air Force has a similar spacecraft called the X 37 B. It's been launched in since 2010. So if that's what China tested, why now it's a great question. We're not even really sure why the United States military is pursuing a space plane like it's been doing for the last Decade or so. Brian Weeden Studies face security issues with the Secure World Foundation. The U. S X 37 B program remains highly classified. Weeden says he believes it's being used to test new sensors and systems for the military. Think about if you're building a brand new satellite, and you've got a lot of fancy new technology that's never been in space before. That's potentially risky. But if you can apply some of that technology in space, let's say in the payload bay of a reusable space plane that could allow you to get a better feel for how about react. McDowell says that space planes which travel many times, the speed of sound, could also potentially helped with the development of so called hyper sonic weapons. Uh, honestly, he thinks China could just be copying the US if the Americans have one of those. That must be a good reason for it. So we better get one, too. The landing of the space plane or whatever it was, is just the latest success for China. McDowell says that recently completed its own satellite navigation system, it has a robotic missions going to Mars and several probes on the moon. China's firing on all thrusters in space on just really increasing its level of involvement on capabilities,.
